Jun 5, 2023 · Simple cars made from craft and recycled materials, including cardboard, compact discs, balloons, rubber bands, straws, plastic lids, and more, can be great tactile models to use for science experiments. With DIY cars, students can explore potential and kinetic energy, forces of motion, Newton's laws of motion, and other science curriculum.
3 days ago · TIP 3: Plan and Sketch. Have kids sketch their car design on paper before building it. This helps them visualize their ideas and make a plan. Ask them to label key components like the wheels, axles, and the mechanism they will use to make it move.
- Some examples of balloon-powered cars made from different materials.
- (Left) An un-inflated balloon does not store any potential energy. (Right) An inflated balloon stores potential energy in the forms of air pressure and stretched rubber.
- According to Newton's third law of motion, when air is pushed backwards out of the balloon (out the end with the opening), there must be an equal and opposite reaction force that pushes the balloon forward (the end opposite the opening).

1 roll of tape (1×5 points = 5 points) Plug your distance in centimeters and total material points cost into Equation 1 to calculate your score. For the car in the example above, with a distance of 25.4 cm and a material points cost of 31, the score is (2×25.4)-31 = 19.8. Round your final score to the nearest whole number.
Apr 25, 2017 · Mousetrap Power. For a simple science project that focuses on kinetic energy sources, build a working model car that is powered by a simple mousetrap. Use foam to build a lightweight body for the vehicle. For wheels, use old DVDs or compact disks. A spring-loaded mousetrap will create the necessary force to propel the car an impressive distance.
Put the large wheels on the back of the car, opposite the snapper arm. 12. Wrap a small rubber band around the axle on either side of each wheel so the wheels can’t fall off. 13. Tie a string very tightly to the snapper arm on the mouse trap. The string should be long enough to just reach to the back axle. 14.
